Whoisit Designer can't load form - "could not load type ...from mscorlib ....due to value type mismatch"
Hi, I'm getting the classic pink error banner when trying to view most of the forms in my solution in VS 2005. Everything was working OK up to yesterday when installed SQL Server 2005 SP1 (which installed a new copy of the .NET framework) and also installed Team Explorer. Tried re-loading everything from source control etc but no solution as yet. These forms were originally written in VS2003 so have the forms designer code embedded. A couple of forms added in VS2005 don't exhibit the problem. Any solutions or workrounds gratefully accepted ! Typical messages in full Could not load type 'System.Runtime.InteropServices.ClassInterfaceType' from assembly 'mscorlib, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934 ...Show All

GregRyanLorenz Create icon?
Hi I have a picture (.png) that I want to convert to an icon. This icon should support 16x16, 32x32, 48x48 px. The icon is for my form... It should be possible to have a more detailed icon when viewing thumbnails in explorer (I think it is 32x32 and 48x48 then ) How do I create this icon in .NET Is there a tool built in Kind Regards The .ico file type is a special Windows file type. You will not find any good converters for free, just really basic ones. I suggested Photoshop because it is a powerful digital imaging application despite its price. When you do find something that converts your image to all those sizes, you need to make sure that your image is bigger or as big as the biggest size you are go ...Show All

Martin Hart Turner How to make a Control inherit the Form backcolor or properties (i.e. font etc)
Hi folks, I would like to know if anyone knows how to make a Custom control inherits the form,upon which it gets dropped, properties like the backcolor, font etc.... By inherits I means will have its own property assign with the current value of the form property. e.g. Control.Font = Form.Font; Also, I want to have the control set up its property at construction time (when the control get constructed - so that it has the same backcolor (in this case ) then the form) Cheers. Seve True transparency is tricky and expensive. Check out this thread for an example. It already works that way. If you don't set the BackColor or Font properties in the constructor or with the designer, ...Show All
elfenland StyleGuidelines/Best Practices for WinForms
Hi- I am fairly new to the Windows Application Development (as I always worked on the Web Applications) and are there any style guidelines available, best practices specific for Windows Application Development I will be using VS.NET 2005 for this applicaiton. Please advise. Thank you. Prabhu From your words, you're a good developer, you're always trying to comply to the rules, aware of the standards. But I doubt that there are white books there stating the industry standards for building windows applications. Maybe the books e.g. Writing Secure Code, something like that may help. Sorry, I should have been clearer in the original request. I am indeed following specific coding guidelines and a well organized projects a ...Show All

Hi, I'd like to print only certain columns of a DataGridView. How would something like this be done I couldn't find any code examples. Thanks Ok i have managed that too. If anyone will run into similar problem here is a way to set it right. In while loop in posted code you must set Do While nRowPos < DataGridView1.Rows.Count - 1 you must delet -1.

hailong1977 Customizing DataGridView Selection Behavior
I'm currently trying to use a datagridview to allow the user to select multiple items from a table. While the multiselect functionality will work for what I want. I would prefer to have the program only change the selection of the current cell when a cell is clicked. Or to basically have the program act as if the user was always holding down the Ctrl key for selection purposes. Additionally, I would prefer if I could also restrict selection based upon the value in the cell being selected. Looking around the net, I found vague references to being able to disable the ordinary selection behavior. However I have not been able to find any information on how to actually do this. If anyone knows how to do this, could they point me in ...Show All
milicica Tutorial loader UI/Code
I'm working on a small smart client program that checks a few things on a workstation to assist local IT techs supporting the networked workstations. The smart client is written in C# 2.0 on the .NET 2.0 framework. Basically, when run, it gathers a bit of information about the PC that a tech would be interested in (such as MAC/IP/Gateway address, drive space, etc). It also runs a few ping checks for various network resources. Anyway, I'm looking to enhance the application by building tutorials into the utility. Allowing the users to click a button and get a list of tutorials on things such as setting up a printer, email, etc... The UI I planned was a left column that would hold a listbox of all the tutorials. When a user clicks the tutoria ...Show All

pwhitaker Getting current row values from my BindingSource in C# VS 2005!!!
Hello, How can i get a current row values from my BindingSource. I have a DropDown List that points to a view, and I set a column of my view to be displayed in my DropDown list and another column as it's value. I need to display another column of my view in a ReadOnly TextBox right near my DropDown list. Thanks so much in advance, Mathew Dear Bonnie Sorry for the delay. Thanks for your time. 1) The reason for not to use concatenation is I want to see them separately not stuck together. Of course, I know that I can simulate it to seem like 2 separate columns, but I was just curious if it can be done (using property sheet or code) in C# VS2005 or not. 2) I would like to correct your c ...Show All
